I went to put some items up to sell on the guild trader, but the sell option is darkened out. I can do the search and check items that is already posted to sell.

Can you please check your guild rank as well as the permissions associate with that rank in the Guild tab? It's possible that the guild leader removed the permission to post items in the guild store for your rank. If that isn't the case, please let us know and we'll be happy to continue looking into it!
I have that, along with the "search" option being greyed out some times (even before having done any search whatsoever).
Closing the store tab completely and reopening seems to fix it.
It usually happens when you go to a guild trader and just look at the first page of warez and don't buy anything and then immediately go to the next guild trader, the menu of the next one will be gray and not interactive.
This bug has been around for several weeks now and as said above, /reloadui will fix this until you get to the next trader.
